隧道施工中粉尘控制方法研究

Study on Dust Control Method in Tunnel Construction

隧道施工作业面的粉尘较大,对环境产生较大的破坏,为了降低隧道施工中粉尘,提高隧道施工中粉尘控制能力,提出一种基于模糊决策的隧道施工中粉尘控制方法。根据隧道工作面粉尘来源,构建隧道施工中粉尘控制的约束参量模型,采用模糊决策方法进行隧道施工中粉尘最小化排放的目标函数构建,结合全局稳定性寻优和模糊参数辨识方法,实现隧道施工中粉尘控制优化。仿真结果表明,采用该方法进行隧道施工中粉尘控制的稳定性较好,收敛性较强,有效的抑制了隧道施工中粉尘排放,降低环境污染。

In order to reduce the dust in tunnel construction and improve the ability of dust control in tunnel construction,A method of dust control in tunnel construction based on fuzzy decision is proposed.According to the dust source in tunnel face,the constraint parameter model of dust control in tunnel construction is constructed,and the objective function of minimizing dust emission in tunnel construction is constructed by using fuzzy decision method.Combined with global stability optimization and fuzzy parameter identification method,dust control optimization in tunnel construction is realized.The simulation results show that the dust control in tunnel construction by this method has good stability,strong convergence,and can effectively restrain dust emission in tunnel construction and reduce environmental pollution.
